mrsn srar JOHN B. HADAWAY, or swamrsoornnn SSACHUSETTS, ASSIGl\lOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW.JERSEY, A CORPORATION OF NEW JERSEY.

T0 aZZ whom it may concern:

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Drying Apparatus, of which the following description, in connection with the accompanying drawings isa specification, like reference characters onth'e drawings indicating like parts in the several figures. f

' This invention rel-ates to drying'apparatus and'is herein illustrated as embodied in an apparatus for transferring parts of boots drying them during'the transferg 3 In the manufacture of boots "and shoes it is customary to applyito parts of thefshoes water, cement, or' other liquidbr iviscous substances Whichrequire that the parts be subsequently dried more or 'less.' For ex ample, it is customary to fold the edges of certain parts of the uppers such as'tips; but

and shoes from one locality to another and before the tips are run through the folding machine, they must vbe prop'erly cemented.

' Freshly applied cement, however, is not as tacky as'that'which has been allowed to dry for an interval; and consequently the'usual procedure is to run the tips through," a cementing machine, whereby the margins to be folded are coatedwi-th cement, then to allow the 'cement'to dry somewhat, and then to run them through the folding machine.

In the drying of the cement and the transfer of the cemented pieces to the folding machine, considerable effort andattention on the part ofthe opera-tor'who does the trans; ferring and times the drying are involved, and the general object of the present invention is to provide a suitable apparatus which may be used to carry pieces of stock slowly from the cementing machine to the folding machine or which may be used in any case in which it is requiredto transfer in a similar manner pieces of stock from one locality to another. It should beunderstood that the cementing andfoldingoperations are referred to merely to promote clearness and brevity and that the apparatus may be used wherever convenient even though no drying effect may be sought. I

According to one featureof the invention there are provided I a conveyor, the buckets of [which pass two localities, from one i to the other of which pieces of stock are to be DRYING APPARATUS;

transferred, a sourceof power to whichthe conveyor may be connected, and automatic means responsive to a predeter'mi'ned extent 'oftrav'el'of the conveyor for disconnecting it from the source of power.' By'properly selecting this, predeterminedextent and by spacing the buckets accordingly,'the parts may be caused to come. to rest always, with one of the bucket-shear one ofthe localities and another near the other locality. If then twom'a'chines which are'adapted to perform sufc'cessiveoperations upon a piece" of work such for 'exampleasa cementing; machine and a folding machine,"arejlocated' respec vtive'ly at the two localities'wreferred to, the

cementing machine operatori'may fill the pieces may without-further attention be transferred from one machine to the other and prop'erly dried during the transfer.

' Another feature of the inventionf com prises means for engaging the conveyorto look 'it from movement after a predeterminedemount oftravel. In the illustrative machine one of the belts of the conveyor is provided'with spacedopenings, and there is mounted onthe frame of. the 'inachine a locking memberv which is held against the belt during the movement of the conveyor and enters an opening when said opening comes into register with the pin.

,These and other features of'theinvention including certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed. out. in the appended claims.

Referring now. to the accompanying draw;

mgs,-, I

Fig. 1 is an elevation ofan apparatus in which the present invention is embodied,

Fig. 2 is a fragmentary view showingthe SWltCh-COIltIOlllIlg and locking mechanism. A bench 3} has' a top, providedwithfan openingftogpermit the'runs of a conveyor to pass, through it f The bench; adapted to they! support at opposite sides two machines which are. to operate successively upon piecesof work, for example a cementing machine at the locality indicated at 5 and a folding machine at the locality indicated at 7 The conveyor comprises two belts,one of which is shown at 9, the. other being directly behind and in register with it,.as is usual, and a plurality of'buckets or receptacles in the form of baskets l1 loosely, suspended from rods 1.3, said rods being held at their. opposite ends in lugs or ears carriedby thebelts. The baskets 11 have skeleton frames, their sides and bottoms being made of wire gauze or other material which will permit the free circulation of. air The belts pass around upper and lower pulleys 17- which are provided in their peripheries with grooves 19 to receive the lugs 15 and thereby prevent slippingof' the belts. There are four of these pulleys, two at the top and two. at the bottom, the upper two being fast to opposite ends of the rotatable shaft 20 the shaft 2:2, but inasmuch as the two upper pulleys and. the two lower pulleys are 1n register with each other in the view shown,

only, one of the upper andone of the lower pulleysappears. I

' In. the position of parts shown, which is a position of rest one of the baskets of the left-hand run. of. the conveyor is located below the top ofthe bench adjacent the 10- cality lnto this basket the cementing machine operator may drop the cemented pieces'of'work until the basket is filled. Another of tlie baskets is located with its bottom substantially flush with the top of the bench near the locality 7. From this basket thefolding machine operator may take the cemented pieces which have traveledslowly from the locality 5 and have been properly dried in the interval The conveyor is caused" to be moved in stages which correspondin extent to the distance between the hask'etsand always comes to rest with two of'the baskets in. the positions which have just" been. described.

' The rods 13, and consequently the baskets 11, are equally spaced around the belts and located. adjacent the rods and respectively at uniform distances therefrom in one of the belts is a series of perforations 21 with which a switch-controlling and locking member'23' co-operates successively to hold the conveyor from movement, the movement of the end of the locking member into a perforation. serving'also to open a switch and thereby withdraw the driving power from the conveyor as will now be described. The shaft oflthe. lower pulleys 17 is rotatable in bearings below the top of the table and thatlof the upper pulleys in bearings considerably above the table, the bearings being formed in uprights 25 which are steadied by braces 27, said braces serving also to guide the filled baskets: and prevent them from tipping. Fast to one of the lower pulleys 17 is a gear 29.xwhich meshes with a worm 31 on a longitudinal shaft This shaft has fast to it a gear 35 which meshes with a worm 37 formed on the end of the armature shaft of a motor 39. Leads ll, 42 are provided to conduct electric current to the motor and lead from any source of current, the lead 42 being broken for the interposition ofa switch the movable member 43 of which is mounted on the lower end of a hand'lever at. This lever is pivoted at 47 near its middle to a bracket on the bench and at itsupper end to the member 23 which is herein shown as a rod loosely slidable in guides carried by the bench. At the end of the rod 23 remote from the pivot 49 is a roller 51' which, when the conveyor is'moving, is arranged to run'on the perforated belt. A. spring 53 tends at all times to hold the switch open andthe rod 28 in its righthand position.

The operation of the apparatus, as thus far described, is as follows: Supposing that the basketwhich is nearest. thelocality 5, where the cementing machine is mounted, has been filled, the cementing machine operator presses the lever 45 therebywithdrawing the end of the rod 23 from the perforation in the belt and closing the switch. At once the conveyor. begins to move slowly in the direction indicated by the arrow with the roller 51. running on the belt and thereby maintaining the switch closed until the next perforation comes into position to permit the roller and the end of the rod to be forced into itby the spring 53, whereupon the source of'power is disconnected and the conveyor stopped exactly in a predetermined position with two of the baskets again respectively adjacent the localities 5 and 7. Further operation ofthe apparatus is merely a repetition of the cycle which has just been described. If the baskets are all empty at the start, it is, of course necessary for the cementing machine operator first to get all the baskets above the bench filled before the folding machine operator will receive any work; It may be that the folding machine operator may at times desire to operate the conveyor, and to permit such operation a rod 123 having an elbow to provide space for passage of the belt is fast to the rod and has an operating handle 223adjacent to the locality 7. By pushing on the handle 223the same resultimay be obtained as has been described above as resulting from manipulation of the lever 45. It will. be understood that the switch may be held clesed by either operator for any desired interval and-that; under these conditions, the conveyor will continue to move;

Although the invention has been set forth as embodied in a particular apparatus for use in transferring work from a certain machine to another, it should be understood that the invention is not limited in the scope of its application to the particular apparatus which has been shown and described or 'to any particular use.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
